, Application filed November 3,1926, Sena-no. 145,926.

I This inventionlrelatesto collapsible chairs, such as used in theatres, automobiles] and for other like purposes. p

I One object of the invention is to provide a chair of the character described having a seat and backinterconnected forcooperativemovement whereby said seat and back may be adjusted to suit the comfort of the occupant of spect to its stanchion supports. I I

Another object of the invention is to prothe chair by simply shifting the'seat withdrevide a collapsible chair of tlie character (10-. 1

scribed, the seat whereof may be foldable to: 1 ward the backand at ithef same time capable when in open position of being shifted back and forth so as tosprovidegreater aisle space where the chairs are combined in rows for theatresorthe likepurposes. 3 A further object of this invention isto provide an improved device of. the character described comprising unit groupsof one or more chairs, each having the movable parts thereof independent of each other, said parts being'arranged'and positioned so that-they cannot cause. injury to theoccupants or the occupants apparel while seated or moving in and about in said chairs.

A still further objectof thi'sinventio'n is. to providehan improved device of the character described comprising few and simple parts, which may be readily assembled to form a chair or group of chairs, and shall be relatively cheap to manufacture, and practical and eflicient in. operation 'to a high degree. i 1

Other objects of this invention will in part be obvious and in part hereinafter pointed out. i

The inventionaccordingly consists in the features of construction, combinations ofelements, and arrangement ofpartswhich will; be exemplified 1n theconstructlonheremaiter described; and of which the scope of appli-' ;cation will be indicated in the following claims. i I i In the accompanying drawing, in which is shownone of the various possible illustrative embodiments of this invention,

(1on Fig. 3 is a view similar to 2 showing the seat and back in folded or collapsed position, one stanchion being removedto expose the movable parts. r

I Fig. 4 is a front elevational view of the improvedchair, showing the seat in folded position. p g; j

Referring in detailto the drawing, 10 denotes a chair embodyingthe invention. adapted particularly for theatres,a and like w purposes. 1 Said chair is seen tocomprise apair of side supports orstanchions 11 made. of angle iron, each being bent into a suitable shape to form a substantial rigid structure, as shown in Figs. 1, 2: and- 41.. Between said stanchions 'there is mounted a movable seat 12 havinga back 13.' For supporting the j I seat between the stanchions, any suitable pivoted means may be provi-ded, such as the fittings14.

Each fitting 14 may have a socket 14:.which is'rigidl secured to a stanchion by'riveted. gusset p ates15, as shown in Fig. 1.v A separate gusset plate andsocket fitting are pro vided to extend from opposite sides of each stanchion (see Fig. 1) so-that each stanchion mavserve as'a support between two adjacent seats in the well understood-manner and as indicated in dotted linesin Fig. 4.

Each pivoted fitting 14 includes a stubshaft 14" extending .from opposite sides of the seat 12 provided with an enlargedhead 14, the latter being engaged in a. socket 14,

as is clearly shown in Fig. 1. Said socket has a slotted opening 14 for entering the shaft head l i and may be provided with a removs able closure plate 14* firmly secured over said slottedopeningfor retaining the shaft head' 14 against accidental displacement. Said shaft sheadvl4 may beformed with a projecting portion having shoulders 1 4? for engag 'ing against suitable abutment stops formed l in the socket 14" for limiting the swinging movement of. the'flseat l2; -The seat 12 i may include .an over-up Ill) holstered structure 12 of any suitable well understood construction and is also supported for slidable movement with respect to the stanchions. For this purpose, a slidable mounting is provided in the form of an angle bracket 16 from which the stub shafts 14 project, as shown in Fig. 1. Said angle brackets form slideway supports on-which the opposite edge portions of the seat 12 ride. The underside of the seat is preferably provided with an edge reinforcing frame 12 which has sections 12 thereof contacting the angle brackets 16 to form a smooth sliding connection. To retain the seat 12 in sliding cooperative position on said angle brackets 16, suitable means is provided comprising an elongated slot 16 in each angle bracket 16 through which extend the stud bolts 17 for holding a retaining plate 18 whereby said seat 12 is'permitted to slide With respect to the angle brackets 16 and stanchions 11 for the purpose hereinafter described.

The back 13 is provided to the stanchions 11 in any suitable manner, as by means of a fitting 19 which may be similar in construction to the fitting 14 which supports the seat 12. Said fitting 19 is seen to comprise a socket 19 which is rigidly secured to an upper part of the stanchion, as shown in Figs. 1 and 41 and is adapted to receive an enlarged head portion 19 of a stub shaft 19", a pair of said shafts being provided to extend from opposite sides of the back 13. Said socket 19 has a slotted opening 9 for entering the shaft head 19 and may be provided with a removable closure plate 19 'firmly secured over said slotted opening for retaining the shaft head 19' against displacement. Said shaft head 19 may likewise be formed with aprojecting portlon having shoulders 19 for engaging,

against suitable abutment stops forxned in said socket fitting 19. Each of said shafts 19' preferably projects from a mounting member 20 which supports the back 13 in position, as shown in Fig. 4. Extending from the lower end portions of each of said mem hers is an arm 20 which extends below the seat and has a longitudinally extending slot 20 therein in which rides a roller 21. Each of said rollers is mounted for rotation on the end of a cross-shaft 22, the shaft being rigidly secured by means of straps on the underside of the seat 12, as is clearlyshown in Fig. 4. The arm 20? is shaped so as to permit cooperative movement between the seat 12 and back 13 in slidably extending or retracting the seat as seen in Figs. 1 and 3 and also to permit collapsibly folding the seat 12 toward the back 13, as is shown in Figs. 3 and 41.

For limiting the sliding movement of the seat 12 in the angle brackets, a suitable adjustable stop 23 may be secured on the underside of the seat against which the outer en d of said brackets 16 abut on retracting the seat shoulders 14 on the projection of the shaft head 14 retain the seat 12 of the chair in vertical or closed position and the back 13 through its engagement with the seat by means of the slottedarm and roller connection is swung inwardly withrespect to the stanchion 11. On swinging the chair into open position, the roller 21' will ride in the slot- 20 of the arm 20 and the parts will be disposed, as shown in Fig. 1. The occupant on taking the seat may easily adjust the chair by applying a slight pressure orforce against the floor with his feet or his hands on the arms 26 of the chair for shifting same 'into a fully extended position, as shown in Fig. 2. In

shifting the seat to its extended position, the back is simultaneously swung with its upper end away from the stanclnons. The occupant may thus adjust the seat and back of the chair to suit his comfort.

Where a number of such chairs are'unite'd into groups constructed in unit groups arranged in rows, the inventor provides means whereby occupied seats may be easily passed for ingress or exit from adjacent seats. The occupant of the seat simply retracts the seat by sliding the seat explained above. It

should be noted that the seat and back of the chair when in collapsed position, as shown in Figs. 3 and 4 not only increases the available space in front of the seat but also behind the back, as is clearly seen from thexdrawing.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use. 7

As various possible embodiments might be made of the above invention, and as various changes might be made in the emobdiment above set forth, it is to be understood that all matter herein set forth or shown in the accent, panying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I
